I had the freon checked and that is very good but when I put the switch on low cooling it's good but when it switches to high the air is still in the low mode?
Your fan blower switch is bad. check with your buick dealership auto parts for price of a fan blower switch and location. they can print out a location for you. don't buy the switch until you check the old one with a volt/ohm meter, unless the switch cost is reasonable.

check voltage directly at compressor if no power needs compressor. how did you check low pressure switch?
SOURCE: Air conditioning not working. Blowing cool air in the back and hot air in the front.
Is there air blowing from the front vents? or can you hear the vacumm change when you change it from heat to cool..... I think it might be a vacumm problem... its a 1997 so the controller vacumm hoses may be cracking.. let us know
Take it to a garage and have them evacuate the system and refill with refrigerant. you have air and non condensibles in the refrigerant system.

I would guess your freon has slowly leaked out, and now simply needs to be recharged. You can buy an AC recharge kit with R134 at Walmart or someplace, and do it yourself quite reasonably. If it doesn't cool after that the way everything else seems to be normal, it would probably have to be the temperature control switch.
SOURCE: Air conditioner intermittently works. check low
I haven't found a really good wiring schematic of the A/C on these cars. But, I can tell you that I had an intermittant problem with my Civic air conditioner that sounds similar to yours.
Mine would work fine in cool and warm weather, but when the outside temperatures got hot, it would quit working. The fan would blow; the system had a good charge on it; and the green A/C indicator light on the A/C on/off switch showed the system as being "on". Despite all the indicators saying the A/C is "on", the compressor clutch wouldn't come on when the weather got hot.
In my case, the reason it stopped working when hot, was due to some poor solder connections at the A/C on/off switch, which is part of the Heater Control Assembly.
I removed my Heater Control Assembly (challenging job), and pulled apart the Heater Control Assembly (more challenging) to access the solder connections for the A/C on/off switch. I resoldered those connections (six solder points) and put everything back together and everything has worked perfectly ever since that time (two years).
I have never seen a wiring schematic that shows this switch with more than three connections, and that is why I haven't posted a schematic for you. If you want the usual schematic(s), you can find one on autozone.com for your Honda.
If you are not comfortable pulling apart the Heater Control Assembly, and soldering those connections, you can install a new assembly which is available on-line. I saw one listed through Majestic Honda for about $240.
I hope this helps.
Good Luck, Mark
